mccorry Posted July 17, 2005 Share Posted July 17, 2005 Just curious how many other people are seeing oil usage from our EJ25 engines and how severe...... Steve Link to comment Share on other sites More sharing options...
melayout Posted July 17, 2005 Share Posted July 17, 2005 I switched to synthetic at 7500 miles. Followed the breakin instructions, except for a few excursions to VVT land. I drive the car as if it is stolen and my baby's mama is in labour. I keed I keeed Link to comment Share on other sites More sharing options...
Jerboa113 Posted July 17, 2005 Share Posted July 17, 2005 maybe I dont know much about turbo cars but isn't oil usage usually a sign of a serious problem? and should NEVER occur in a new car? or even a car newer than 10 years old for that matter?

mccorry Posted July 17, 2005 Author Share Posted July 17, 2005 Seems to be more of an issue of blowby with a turbo engine. Mine has done it from day 1..... I have heard many others with the same problem...hence the poll.... I never had another car the used a drop, including a 240k mile Pontiac and my 164k Z28.

Jerboa113 Posted July 17, 2005 Share Posted July 17, 2005 meh, wish I'd have known that before buying, gonna be burning oil like a 70s car in 5 years? I guess ya just dont mention that when you put it up for sale later eh? lol well what I already knew was NO car is perfect, this one is the closest on the market for me.

mccorry Posted July 17, 2005 Author Share Posted July 17, 2005 Oil consumption isn't necessarily a forecast for future trouble. My understanding is that the WRX's and STI's have the same issue. More than likely, it is just due to the extra blowby due to the boost and the ring and ring land design. It doesn't mean that you are going to have failures down the road. More than likely, the consumption rate will decline as the engine breaks in. I am currently at 16,000 miles and I am using about 1/2 to 3/4 quart between changes (5,000 mile intervals). Originally, I was using more like a quart..... Link to comment Share on other sites More sharing options...
rc0032 Posted July 17, 2005 Share Posted July 17, 2005 I need ~1/2 quart every 1500 miles. I change every 3K with 5W30 What weight oil are you using? Link to comment Share on other sites More sharing options...

Whitestar Pilot Posted July 17, 2005 Share Posted July 17, 2005 I made the switch to Mobil 1 synthetic at 1800 miles. My daily driving habits are short trips in heavy traffic, so although my car is low mileage, the factory oil was over 3 months old at the time I made the switch. I then went 6 months and 4,000 miles on the first Mobil 1 change, swapping the oil out again at 5,800. The car is now at 6200 miles, and its never used any oil. If you think your Legacy is burning oil, let it sit for a couple hours before checking the dipstick level. Link to comment Share on other sites More sharing options...
Ed_T Posted July 17, 2005 Share Posted July 17, 2005 Good reports of lowered // eliminated consumption with GC 0w-30. Link to comment Share on other sites More sharing options...
doogdog Posted July 17, 2005 Share Posted July 17, 2005 I check my oil every time I fill up, never been down. I now have 6300 miles and have been using Mobil 1 5W30 since 3000 miles. Rick Link to comment Share on other sites More sharing options...
Ed_T Posted July 17, 2005 Share Posted July 17, 2005 Just read on another board (sorry lost the link) a fellow used M1 5w-30 for all of the 98,000 miles his Chevy's 4.3L engine lasted. Regular changes, etc etc etc. I'll try to post the link. Link to comment Share on other sites More sharing options...

edmundu Posted July 18, 2005 Share Posted July 18, 2005 All internal combustion engines consume oil! You may not be able to detect it, due to a couple of reasons like: 1. You have some fuel dilution which thins the oil, and covers itself by still showing full on the stick. 2. The oil has suspended contaminates, which also help to replace the oil that was lost due to consumption. 3. Oil oxidizes as it gets exposed to the byproducts of engines, and therefore thickens some. What I am saying is, engines by design, use some oil. Some use more than others, BUT ALL use some. I have around 26k on my car, and I have had oil analysis' on almost all changes. And only just recently, did my consumption come down from about .75-1.0 qt per 5k,to .25 qt for 4k. I'm currently using Pennzoil Platinum 10w30, and so far I like this oil best! I have used Mobil 1 10w30, Castrol (GC) 0w30, Castrol GTX 5w30, Chevron Supreme 5w30&10w30, and Penn Dino 10w30. Not in any particular order, but I favored the Chevron/Penn dino, and the Platinum on synthetics. I will be due for an analysis with the Platinum fill, in about 2k or about a month. I will post my results, which I expect to be real good! Bottom line, do not be overly worried about some oil consumption, unless it is excessive, like 1qt per 1k, after being broken in. During breakin, I used almost 1qt per 1.5k, for the 1st OCI, then it slowly went down to the current .25qt per 4k levels. I'm not an oil expert, but I have been reading the BITOG forum, and there is a wealth of info for anyone interested in anything oil related!

felix1357 Posted July 18, 2005 Share Posted July 18, 2005 Huh this thread is funny I just checked My oil yesterday after about 5k and saw that it was down about 3/4 QT and thought wonder if this is normal. Log on this morning and here it is car has 9,800 miles on it. The last oil change after 3000 miles had no oil loss. Link to comment Share on other sites More sharing options...
Ridgeracer Posted July 18, 2005 Share Posted July 18, 2005 I'm using 5w30 dino oil and i'll maybe see about a 1/4 quart loss every 3K miles... "Gimme mines Balboa...Gimme mines".....Clubber Lang - Mr. T Link to comment Share on other sites More sharing options...
frankjdattco.com Posted July 19, 2005 Share Posted July 19, 2005 I did about a 1000 miles going to virginia beach last week and stayed at the same level. Which is pretty good considering I was about 500 miles away from my suggested oil changed when i got back. Link to comment Share on other sites More sharing options...

mccorry Posted July 19, 2005 Author Share Posted July 19, 2005 My buddy worked for Lubrizol, who makes most of the additives for engine oil (detergents, flow modifiers, etc.). He told me that Valvoline and Pennzoil use the most additives (good) vs. Quaker State which uses the least (bad). This was about 10 years ago though.... Anyhow... I am a loyal Valvoline user.....

edmundu Posted July 19, 2005 Share Posted July 19, 2005 Any particular reason why you like the Penzoil Platinum the best? I'm about to go shopping for my next oil change and was wondering what to go with. Ken Pennzoil uses very high quality base oils in their Dino's, and this latest Platinum is supposedly EOP, kinda like a new generation PAO oil! There haven't been very many OCI analysis's done on it, but I trust Penn. and I remember back a few years ago when they had the absolute best synthetic out there called Pennzane? not sure on the spelling. This new Platinum is said to have no Grp III in it, so it is a true synthetic, much like Castrol GC, M1, Amsoil, Redline, etc... But also cost was a factor! I was able to get it for $1.59 qt, after a $15 rebate! At that price, there are no downsides! I will be getting an analysis done on it soon, like within a month or so. It will have at least 6k on it, maybe even 7k. My last few analysis's revealed that I could go even further,(8k), but I will play it conservatively, until I find out how good it is. PS Currently you can get a $10 rebate on a case purchase, until July 31st. This will make it less expensive than pretty much any OTC synthetic.

If it were there, they'd be bragging about it, one might think. http://www.pzlqs.com/Tech/Pdsheet/DomesticMarketing/EngineOils/Pdf/PlatinumFullSyntheticMotorOil.pdf I suspect this is a GROUP III oil.

Not very easy, but if you visit BITOG and search for Johnny, he works for Pennzoil and has some insider info, you will be able to judge for yourself.

TSiWRX Posted November 4, 2005 Share Posted November 4, 2005 Well, I got back just about as much as I expected - which is to say, darned near all of it, on my last oil-change of Mobil1 10W30. Currently on Mobil1 5W30, we'll see how this goes. <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...
